Answer:
200+200+1,000+6,000 = 7,400 - 1,200 = 6,200
6,000+200=6,200
Step-by-step explanation:
so 200 plus 200 equal to 400 plus 1,000 equal to 1,400 plus 6,000 equal to 7,400 and then 7,400 subtract by 1,200 equal to 6,200.
and 6,000 plus 200 equal to 6,200.
Hope this helps! :)
Answer:
assuming the comma is meant to be a decimal...
It would be 2.9
Step-by-step explanation:
the place right after the decimal is the tenth place. the 5 rounds up the 8. don't worry about the 2. so the 8 becomes a 9 and you leave off the rest because you are only worrying about the tenths place.
The question is incomplete. The complete question is :
Cylinders A and B are similar. The length of the cylinder A is 4 mm and the length of cylinder B is 6 mm. The volume of cylinder A is 20mm3. Calculate the volume of cylinder B.
Answer:
67.5 
Step-by-step explanation:
Given that :
Cylinder A and cylinder B are similar.
Let volume of cylinder A = 20 
We know the volume of a cylinder is given by V = 
where, r is the radius of the cylinder
h is the height of the cylinder
We have to find the scale factor.
The length scale factor is = 

Area scale factor 

∴ Volume scale factor 

Therefore, the volume of cylinder B is 
= 67.5 
Answer:
5b + 12c
Step-by-step explanation:
-5a +5 a = 0
12b-7b = 5b
12c= 12c
therefore you have the expression 5b+12c
